ADT7484A/ADT7486A

Digital Temperature Sensor

with SST Interface

The ADT7484A/ADT7486A are simple digital temperature sensors

for use in PC applications with a Simple Serial Transport (SST)

interface. These devices can monitor their own temperature as well as

the temperature of one (ADT7484A) or two (ADT7486A) remote

sensor diodes. The ADT7484A/ADT7486A are controlled by a single

SST bidirectional data line. The devices are fixed-address SST clients

where the target address is chosen by the state of the two address pins,

ADD0 and ADD1.
